WHISTLE.

. Specification of Letters Patent.

Patented ar. 30, 1915.

Application filed September 16, 1913. Serial No. 790,088.

To all whom it may concern:

Be it known that I, SAMUEL DRESSLER, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented certain new and useful Improvements in \Vhistles, of which the following is a specification.

My invention relates to musical instruments and more particularly to whistles designed to be held in the mouth of the user.

A whistle constructed in accordance with my invention comprises a mouth-piece and a resonator, or sounding-box, connected therewith, and provides a whistle of greater sonority and of more musical tone than those heretofore constructed.

My invention consists in the parts improvements and combinations hereinafter described and claimed.

In the accompanying drawings, in which like numerals designate like parts throughout, is shown the form of whistle construct ed in accordance with my improvements.

Figure 1 is a top plan view of the simplest form of whistle constructed in accordance with my invention, and Fig. 2 is a side view thereof and Fig. 3 is a view in perspective of a modified form of whistle.

In the drawings, 1 represents the mouth piece, which is preferably closed at its rear andis composed of separated plates 9. and 3 spaced apart and provided with customary registering openings 4. This mouthpiece is enlarged toward its rear end so that it can readily be held in the mouth of the user. At the front of the mouth-piece 1, I provide a resonator, or sound-box, 5 connected therewith by the separated plates 6 and 6. Plates 6 and 6 are provided with openings 7. The bead 8 acts as a guide so that when whistle is-placed in the mouth of the user it will be in a position ready for use. Said bead 8 extends to the edges of the plates 6 and 6' and provides an enlarged transversely curved opening therebetween, and such 'curved transverse passage of extra height contributes in a large degree to the effectiveness of the whistle. The

sound-box or resonator may be ofany desired conformation, cylindrical preferred as shown in the accompanying drawings. The resonator, or sound-box, may be provided with closures 9 as shown in Fig. 3 at the ends thereof which may conveniently be made by bending over a section of the resonator which is left projecting on the same as stamped from sheet metal, as is the usual practice in the construction of these devices or the ends of the resonator may be inclosed by the fingers of the user as is designed to be the practice with the form of device shown in Figs. 1 and 2.

A whistle constructed in accordance with my improvements, hereinbefore set forth, is extremely easy and convenient of manipulation, gives forth a soft, melodious tone which may readily be changed throughout a wide range of notes. By permitting a portion of the air imprisoned in the soundbox to escape through openings 7, currentsof different and varying strength may be caused to be emitted through the ends of sound-box 5 and the adjoining separated plates 6 and 6. This fact adds greatly to the efficiency ofthe device and to the quality of tone produced.

Having now described my invention, I claim:

A whistle comprising av mouth piece formed of two separated plates provided with registering openings and open at the front and sides, said plates being extended beyond the said mouth piece to form a resonating chamber, beads formed in the material of said upper and lower plates between the mouth piece and resonating chamber, said beads being curved-to conform to the curve of the lips of the user and extending to the edges of the plates to provide an enlarged transversely curved opening therebetween extending to the edges of the plates, and said resonator being open at the sides beyond said beads, substantially as set forth.

This specification signed and witnessed this 18 day of August 1913.
